SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
The supernova was about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole, based on current stellar evolution models. The supernova is located near a prominent HII region, NGC 5461, in an outer spiral arm of the bright galaxy. [3] By 22 May 2023, SN 2023ixf had brightened to about ...
The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
SN 2023rve is a type II supernova that happened in the 10th magnitude barred spiral galaxy NGC 1097 on September 8, 2023. [1] Scientists from the McDonald Observatory in the state of Texas, United States, have observed the supernova and conducted photometric measurements, they described it to be the brightest supernova in the sky as of September 12, 2023.
T Coronae Borealis, also known as the "Blaze Star," is actually a pair of stars located 3,000 light-years away. The star system is a recurring nova, with Earth-visible explosions every 79 to 80 ...
The last supernova directly observed in the Milky Way was Kepler's Supernova in 1604, appearing not long after Tycho's Supernova in 1572, both of which were visible to the naked eye. The remnants of more recent supernovae have been found, and observations of supernovae in other galaxies suggest they occur in the Milky Way on average about three ...
Insets at lower right show one epoch of Webb observations, while the inset at left shows a Webb image of the central supernova remnant released in 2023. "Even as a star dies, its light endures ...
